Low-Flow Photoelectric Duct Smoke
Detectors for FireWarden-100
Section: Addressable
GENERAL
ND-100 and ND100R photoelectric duct smoke detectors are
used exclusively with the NOTIFIER FireWarden-100 (NFW-
100) addressable control panel. They provide low-flow technology that enables duct smoke detection throughout a broad
range of airflow environments in HVAC applications. The lowflow technology can detect smoke at air speed velocities of
100 feet per minute (0.5 m/sec) or greater, while continuing
the same reliable performance to 4,000 feet per minute (20.32
m/sec). The intelligent low-flow duct detectors sample air currents passing through a duct and gives dependable performance for shutdown of fans, blowers, and air conditioning
systems, preventing the spread of toxic smoke an fire gases
through the protected area.
ND-100 and ND-100R provide a remote alarm output for use
with auxiliary devices, such as the RA400 remote LED annunciator, as well as remote test capability with the RTS451 or
RTS451KEY Remote Test Stations. The ND-100R features a
Form-C relay.
APPLICATIONS
Duct smoke detectors have specific limitations, they are:

ND-100
FEATURES
• Air velocity rating from 100 to 4,000 feet per minute (0.5 to
20.32 m/sec).
• Patented telescopic sampling tube.
• Easily accessible code wheels for addressing detector.
• Outside mounting tabs.
• Mounts to round or rectangular ducts from 1’ to 12’ (0.3 to 3.7
meters) wide.
• Transparent cover for convenient visual inspection.
• Powered outputs for remote LED, and remote test and
sounder.
• Two Form-C auxiliary contacts (ND-100R).
• Patented cover-tamper trouble signal.
• ND-100R requires both com line power and one of the
following: 24 VAC/VDC or 120/220 VAC for operation.
INSTALLATION
Refer to installation manuals for control panel and duct
detector for detailed information or to install equipment.
Wiring: For signal wiring (the wiring between detectors or
from detectors to auxiliary devices), it is recommended that
single conductor wire be no smaller than 18 AWG (0.78 mm²).
This document is not intended to be used for installation purposes. We try to keep our
product information up-to-date and accurate. We cannot cover all specific applications or
anticipate all requirements. All specifications are subject to change without notice.
For more information, contact NOTIFIER. Phone: (203) 484-7161 FAX: (203) 484-7118
ND-100R
The duct smoke detector terminals accommodate wire sizes
up to 12 AWG (3.1 mm²). Flexible conduit is recommended for
the last foot (30.48 cm) of conduit; solid conduit connections
may be used if desired.
Smoke detectors and alarm system control panels have specifications for Signaling Line Circuit (SLC) wiring. Consult the
control panel specifications for wiring requirements before
wiring the detector loop. The ND-100 and ND-100R detectors
are designed for ease of wiring; their housing provides a terminal strip with clamping plates.

NOTES: 1) Jumper J1 shunt must be installed for 2-W applications. J1 shunt must be removed
for power PCB supervision. Note that removal of shunt without adding external power will prevent
communications to the panel over the SLC. 2) External power of 24 V AC/DC or 120/220 VAC
must be connected in order to power all remote horn or strobe accessories.
